Tin(IV) chloride mediated [3 + 2] cycloaddition of allylgermanes to α-dicarbonyl compounds proceeds highly stereoselectively to give tetrahydrofurans in good yields.
We recently reported on the successful use of the Karstedt catalyst for the synthesis of organofunctionalized disilazanes, and the aim of this work was to check the activity of this catalyst in the preparation of novel unsymmetrical boron‐ and germanium‐functionalized disilazanes. High selectivity, relatively mild conditions, and the simplicity of the experimental techniques are favorable features
